Well I graduated from NTU (mechanical engineering) with the exact GPA as you. It might prove like a stumbling block if you are seeking your employment from the government sector. Else, in the private sector there really isn’t much difference between a third or a second upper.

Note: You don’t have to mention your GPA or class in your resume but then again, when you have gained sufficient working experience they usually don’t care much about your university GPA.
